opn_haproxy_configtest

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Describes internal mechanism ('haproxy -c') and return type (dict with 'status' key). No annotations provided, so description carries burden; could add more detail about error reporting or side effects.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Five concise sentences with no waste. Front-loaded purpose, then usage, mechanism, and return. Ideal structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers purpose, when to use, how it works, and return format. Output schema exists, so return details are partially covered. Lacks prerequisites or error handling nuances, but sufficient for a simple validation tool.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

No parameters. Schema coverage is 100% (empty). Baseline 4 applies per rules.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the tool validates HAProxy configuration syntax before applying. Distinguishes from sibling opn_reconfigure_haproxy by explicitly saying 'Use this BEFORE calling opn_reconfigure_haproxy'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly advises using before opn_reconfigure_haproxy. Lacks explicit when-not-to-use or alternatives, but the directive is clear and actionable.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
